By the mid-1990s more than 90 percent of American households had a microwave, and nearly 9 million microwave ovens were being shipped annually.
The historical average height of an average height is 5'9.

In the US the average number of airplanes in the sky on an average morning is about 4000
The frequency at which a microwave oven operates, about 2,450 MHz, has a wavelength of about 12 cm.
A photon of this wavelength has an energy of about 10 ^ -5 eV.
. Longer, and a period that is longer
10 centimeters or less If you mean "microwave oven", those operate at the frequency of 2.45 GHz, where the wavelength is 12.24 centimeters.
is a system of equipment used for microwave data transmission.
They use different wavelength and frequency
The wavelength used in the microwave oven is about 12 centimeters. (rounded) In the early days, there were radar systems that used wavelengths longer than that, but there haven't been any for several decades now.
Inches (microwave) vs. Feet (Radar).
Scientists group electromagnetic waves into categories according to their wavelength. Technically a radio wave has a longer wavelength then a microwave but that's the only fundamental difference. They are both electromagnetic waves.
10 centimeters or less If you mean "microwave oven", those operate at the frequency of 2.45 GHz, where the wavelength is 12.24 centimeters.
Microwaves are wavelengths of light that are shorter than radio waves, but longer than infrared light waves. The wavelength range is 1 meter to 1mm. One particular wavelength is optimum for being absorbed by water, and this is what "microwave ovens" are tuned to produce. This is 2.45 GHz, which is about 12.2cm wavelength.
Electromagnetic wavelength = speed/frequency = 3 x 108/6 x 1010 = 5 mm
